Portage Lake is situated near the center of the Keweenaw Peninsula and is connected to Lake Superior via lengthy (> 7 km) navigation channels. Using moored thermistor records and meteorological data, we examine how changes in lake stratification are related to surface winds and heat flux. Frequent episodes of full water column mixing are observed throughout the summer. Convective mixing through...
Mixtures of quantum fluids, that is gases or liquids, are considered with the emphasis on conditions characterizing stability mixtures. The mixtures, can be formed by cold atoms molecules, assumed to requiring description using techniques, but not so exhibit superfluidity superconductivity. Reviewing such normal systems important for comparison these of, e.g., Bose-condensed behavior observable...
Meltwater from the Greenland Ice Sheet often drains subglacially into fjords, driving upwelling plumes at glacier termini. Ocean models and observations of submarine termini suggest that plumes enhance melt and undercutting, leading to calving and potential glacier destabilization. Here we systematically evaluate how simulated plume structure and submarine melt during summer months depends on r...
A strong relationship is observed between synoptic weather systems and atmospheric forcing of the ocean as estimated from buoy measurements made on the North Carolina inner shelf during August and October-November 1994 as part of the Coastal Ocean Processes (COOP) Inner Shelf Study. Synoptic variation (timescales of days to weeks) in the meteorological time series was primarily associated with ...
The present work analyses theoretically and numerically fire plumes evolving in a two-layer stratified environment. ambient fluid consists of lower cold (heavy) layer an upper warm (light) with sharp interface. plume is controlled by the heat release rate Q. Depending on density interface location, temperatures layers source conditions, can rise indefinitely or be captured stratification. To de...
Lakes are traditionally classified based on their thermal regime and trophic status. While this classification adequately captures many lakes, it is not sufficient to understand seasonally ice-covered the most common lake type Earth. We describe inverse stratification in 19 highly varying lakes derive a model that predicts temperature profile as function of wind stress, area, depth. The results...
